I have this file https://uploadnow.io/f/mLKhQKj and I want to keep only what is in front like a skin or so. As you can see the column is full. I press Z and the model turn with that face up. So, is there a way to combine all elements in one single face/mesh/skin and all elements that are in the back like unseen half of the column and apples to be deleted ?
1- apply all modifiers by selecting everything "ctrl+a > visual geometry to mesh" and join everything with "ctrl+j"
2- draw a plane on top of your model
3- add desire amount of subdivision on plane set mode to simple and apply subdivision modifier
4- add "shrinkwrap" modifier on plane set method to project check positive and negative set target to your model
5- apply everything and hide or delete your original model.
6- if your problem have solved accept this answer and like it
also you can describe more about your case maybe someone can explain better like what you wanted to do with this model next .
I dont know if there is a UI command for that, but you could run a little script to delete all faces not pointing into the positive z-halfspace. Open the
Scripting tab, create a new python text file and paste this script:
import bpy, bmesh
mesh = bmesh.from_edit_mesh(bpy.context.object.data)
for face in mesh.faces:
face.select = face.normal.z < 0
Select your object
panno_1000128_pesn and run the script. All faces pointing downwards are deleted. If you also dont want to keep straight vertical faces, you can replace
Edit: before running the script, you should also recalculate the normals of your model, its a bit messed up. Go in face edit mode, select all faces and do
Mesh > Normals > Recalculate Outside.
